OEM Carrier 3-Pole Contactor 25A 115V Coil for Model 09DK064600 (HN53CB115)

This is the genuine OEM 3-pole contactor for the Carrier 09DK064600 commercial HVAC system. The contactor is the high-voltage switching relay controlled by the 24V–120V low-voltage circuit — it closes to deliver line voltage to the compressor and fan motors whenever a call for cooling is made. A failed contactor typically presents as a system that won't start (no click, no compressor hum), chatters loudly during operation, or shows visible pitting and welded contacts on inspection. Replacing it promptly prevents damage to the compressor windings from voltage irregularities.

• Specs: 3-Pole | 25A FLA / 35A RES | 120VAC Coil | Load-side rated 240/480/600V | 150/125/100 LRA | Hartland Controls HCCY3XT01DT103 equivalent
• OEM vs Generic: This genuine Carrier OEM part meets exact factory coil pull-in voltage and contact material specifications. Aftermarket contactors can use inferior silver-alloy contacts that pit faster under high-inrush loads, shortening service life significantly.
• Install difficulty: 3/5 — Requires full system lockout/tagout before service. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify 0V before touching load terminals). Always photograph wiring before disconnecting. Coil wires are low-voltage (120V); line terminals carry full load voltage.
• Warranty & Shipping: 1-year OEM manufacturer warranty. Ships same business day from our warehouse. Free shipping on qualifying orders.

Compatibility: Designed for the Carrier 09DK064600 commercial condensing unit. Also replaces legacy part numbers HN53TB115, HN52KC016, and HN72AZ301. Verify pole count, amp rating, and coil voltage against your unit's wiring diagram and data plate before ordering. Our fitment team is available to confirm compatibility before you buy.
